Specification of Letters Patent.

Patented June 23, 1908.

Application filed October 17, 1907. Serial No. 397,897.

To all whom it may concern:

Be it known that I, CALVIN R. DAVIS, of South Bend, in the county of St.Joseph and State of Indiana, have invented certain new and usefulImprovements in Flows; and I do hereby declare the following to be afull, clear, and eXact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to plows and more particularly to sulky plows ofthe reversible type which employ two independently movable plows andplow-beams.

With many plows of the type above referred to,'as heretoforeconstructed, it has required considerable effort on the part of theoperator to cause the plow points to properly enter the ground and insome cases the desired depth of furrow could not be insured.

It is the object of my invention to obviate these insufficiencies and toprovide means whereby the operator can, with slight effort, insure theproper entrance of the points of the plows into the ground when theplows are lowered and to cause a proper and uniform depth of furrow tobe made as soon as the plows shall have been lowered and the forwardprogress of the machine begun.

ith these objects in View my invention consists in certain novelfeatures of construction and set forth In the combinations of parts ashereinafter and pointed out in the claims.

accompanying drawings, Figure 1 of a reversible plow embodymg myimprovements. Fig. 2 is a rear view, and Figs. 3 and 4am enlarged detailviews illustrating the manner of attaching the foot lever to theplow-beam.

1 represents an arch, to the depending members of which brackets 2 aresecured. The rear ends of the side-members of a rectangular frame 3 aresecured to the brackets 2. This frame is disposed in an inclinedposition; projects forwardly from the arch and is secured at its forwardend to a tongue 4 by means of a bracket 5,the rear end of said tonguebeing connected with arch 1.

A bracket 6 depends from the central portionof the arch 1 and isprovided with bearings for the inner members of two bails. 7,- the outermembers of said bails having bearings in the brackets 2. Arms 8 aresecured between their ends, to the outer members of the respective bails7, and at the lower ends of the arms 8 other arms 9 are provided andconnected at their rear ends with the horizontal portions of the bails7. At the juncture of the arms 89, axle stubs 10 are vided for carryingWheels 11.

A plow-beam 12 is mounted, at a point between its ends, upon therespective bails 7 and the forward ends of the plow-beams are providedwith suitable draft devices.

- A toothed-segment bracket 13 is secured to each side member of therectangular-frame 3. Hand-levers 141 are pivoted to the brackets 13 andthe lower ends of each hand-lever is connected, through the-medium of apitman 15, with the upper end of arm 8. Means are thus provided wherebythe operator can, when in position upon the seat 16, raise and lower theplows independently of each other by manipulating the hand-levers 14.

For the purpose of causing the plow points to properly enter the groundwhen the plows are lowered, I provide foot-levers 17,one of such leversbeing secured to the forward portion of each plow-beam and the up erends of said foot-levers projecting upward y through the rectangularframe 3 so as to be disposed within convenient reach of the operator. Toconnect the footlevers with the plow-beams, I employ brackets 18 andclamping-bails 19. The inner face of each bracket 18 is preferablyrecessed to receive the lower end of the foot-lever and the outer faceis rovided with a curved or conveX seat 20 for tie plowbeam. The arms ofthe bail 19 pass through the bracket 18 and the lower portion of thelever and are provided with threaded ends to receive nuts 21. It isapparent that when the nuts 21 are screwed home the foot-levers will besecurely clamped to the plow-beams. By providing the brackets 18 withcurvedseats against the plow-beams, the foot-levers can be adjustedlaterally by loosening a nut on one bail arm and tightening the nut onthe other bail arm. I

In operating the machine, the operator will press down on a foot-lever17 at the same time that he will be pressing forward on a hand-lever 14.By pressing the foot-lever, the front end of the plow-beam will bedepressed, thus placing the plow on its point and when in that positionthe hand lever may be pressed forward and locked with but slight effort.The plow will enter the ground and reach a full depth of furrowpromptly.

Having fully described my invention what pro- I claim as new and desireto secure by Letters-Patent, is,

1. The combination with a plow beam provided at its rear end with a plowand means for pivotally supporting the plowbeam between the ends of thelatter, of a foot-lever attached to the forward portion of theplow-beam, and means for effecting lateral adjustment of the upper endof said footlever.

2. The combination with a plow beam provided at its rear end with aplow, means for pivotally supporting the plow-beam between the endsthereof and means for raising and lowering the plow-beam and plow, of afoot-lever, a bracket secured to said foot lever, said bracket having aconvex-seat against the forward portion of the plowbeam, and means forclamping said bracket and foot-lever to the plow-beam.

i P l 0 3.- The combination with a plow beam provided at its rear endwith a plow, means for pivotally supporting said plow-beam between theends thereof and means for raising and lowering the plow-beam and low,of a foot-lever, a bracket to receive the lower end of said foot-lever,said bracket having a convex-seat against the forward portion of thelow-beam, a bail embracing the plow-beam and having its parallel memberspassing through the bracket and said lever and nuts on the free ends ofthe bail members.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.

I CALVIN R. DAVIS.
